Widespread testing for PCE vapors in Troy (OH)

Thanks to CPEO for this tip.
According to this Dayton Daily News (OH) report:


The U.S. Environmental Protection Agency will begin testing for a likely carcinogen in the basements of homes, schools, churches and businesses in what could be the largest case in Ohio.

Randy Waterworth of the state EPA said Thursday the federal effort would start with three schools — Forest and Van Cleve elementaries and St. Patrick School — in about 20 square blocks east of downtown.

Steve Renninger of the federal EPA in Cincinnati said the testing should start in the next two weeks.

Officials have known for a number of years that soil in the area was contaminated with tetrachloroethelyne (PCE) in two plumes. One plume may have originated from a former dry-cleaning site near the southeast quadrant of the Public Square. The second appears to have originated near Spinnaker Coating and Hobart Cabinet.

PCE is a dry-cleaning solvent and a metal degreaser. Exposure to PCE over 30 or more years is thought to cause cancer in humans, based on animal testing.

Only in the past two or three years have scientists discovered that PCE often turns to vapor in the soil and can work its way into basements. City tests of 11 basements in April showed PCE vapor readings from twice to 189 times the recommended level.
